Umm, then what is it?
Well, I copy-pasted the unknown character into notepad++ and it showed "ETB", so i googled "ETB character" and got the ascii "End Transmission Block" control charachter, which can be made by pressing alt+0,2,3 on the keyboard.
Somehow you must've accidently made that in the script, just redo the space between the , and " and it won't give an error anymore.
